c# - Filestream.write 不起作用

Question

我用下面的代码写在*.txt文件上，但是没有任何反应。甚至，也不异常(exception)。

        FileStream fs = new FileStream(@"D:\file.txt",FileMode.OpenOrCreate,FileAccess.Write,FileShare.None);    //Creating a stream with certain features to a file

        StreamWriter writer = new StreamWriter(fs);    //Use the fs to write

      //  writer.WriteLine(Text.Text);  none of the following methods works
        writer.Write("aaaaaaaaaaaa");

        fs.Close();

谢谢

尝试像这样将其包含在 using block 中:

using ( FileStream fs = new FileStream(@"D:\file.txt",FileMode.OpenOrCreate,FileAccess.Write,FileShare.None))
using (StreamWriter fw = new StreamWriter(fs))
{
    fw.Write("aaaaaaaaaaaa");
} 

StreamWriter 在将数据写入底层流之前缓冲数据。您需要通过处理 StreamWriter

来刷新缓冲区
